Abstract
V magistrskem delu obravnavamo dve različni tehnologiji izdelave izoliranih statorskih paketov, pri čemer se osredotočamo na proizvodne stroške izdelave. Trenutni izdelovalni procesi vsebujejo velik delež ročne montaže, ki pa zaradi povečanega povpraševanja po obravnavanih izdelkih ni več optimalna. Poraja se vprašanje, ali je trenutno tehnologijo izdelave smiselno zamenjati z drugo, v večji meri avtomatizirano tehnologijo. V mislih imamo proces zabrizgavanja paketov, s katerim bi nadomestili procesa laserskega varjenja in ročnega izoliranja statorskih paketov v trenutni izdelovalni verigi. Obstoječe procese smo analizirali s sistemom vnaprej določenih časov Work-Factor in s snemanjem časa v proizvodnji, pri čemer smo spremljali delo več delavcev. S pridobljenimi podatki smo analizirali izkoriščenost trenutnih proizvodnih procesov ter določili njihovo zmogljivost, ki je osnova za izračun proizvodnih stroškov izdelave. Zmogljivost alternativnega izdelovalnega procesa smo določili intuitivno, na podlagi izkušenj s podobnimi izdelki. Ugotovili smo, da so proizvodni stroški izdelave z alternativno tehnologijo izdelave nižji kot s trenutno tehnologijo. Iz izračunanih prihrankov smo ugotovili, da se nam potrebna investicija v nova delovna sredstva povrne po 20.000 izdelanih kosih, kar pri trenutnem obsegu proizvodnje traja približno 2 leti.

Title:Design and cost comparison of two technologies for the production of an insulated stator package
Abstract:
This thesis deals with two different manufacturing technologies of an insulated stator package, whereby the production costs are the main focus. Currently used manufacturing processes contain a substantial amount of manual assembling, which is no longer optimal, due to increased production numbers. For this reason a question comes to mind, if a substitution of manufacturing technology makes sense. Stator insulation can be made with automated overmolding process, which has the potential to substitute both laser welding and manual insulating of stator package, that are currently used. We analysed existing production processes with the system of pre-determined times Work-Factor and time recording method, whereby work of multiple workers was analysed. Acquired data was used to determine process capacity, which is the main factor in production costs calculations. Capacity of alternate production technology was determined intuitively, based on experience with similar products. We found out, that the production costs are lower with alternative manufacturing technology. For implementation of the alternate manufacturing technology in production, an investment in new working resources has to be done. That investment refunds at 20000 produced units or 2 years at current production rate.
